Electroencephalographic correlates of prolonged locomotor performance of professional musicians
Brabencová, Zuzana ; Pánek, David (advisor) ; Maršáková, Kateřina (referee)
Title: Electroencephalographic correlates of prolonged locomotor performance of professional musicians Summary: The aim of this work is to verify the presence of alpha activity in the electroencephalographic recording during prolonged (20 minute) violin play and compare its morphological and topical parameters with the native EEG record before and after the performance. Research sample consisted of five professional violinist in the age range of 25- 60 years. The results showed the occurrence of alpha activity for four of five probands, in one case with a very low incidence. There has been also demonstrated changes in the distribution of alpha activity from parietooccipital areas before the preformance to central areas during the play and immediately after finishing. All probands showed increased amplitude of the alpha activity immediately after finishing. The obtained results confirm the changes of morphology and the changes of topic alpha activity during cognitive activities and at the onset of central fatigue during physical aktivity described in literature. These changes were demonstrated by increasing the amplitude of alpha activity and the shift from parietooccipital areas to central areas. Keywords: EEG, alpha aktivity, violin performance, brain mapping

The usage of qi gong for training of perceiving body schema
Pospíšilová, Eva ; Pánek, David (advisor) ; Véle, František (referee)
Title: The usage of qi-gong for training of perceiving body schema Summary: The goal of the work is to prove the presence of alpha activity in the electroencencefalographic record throughout the duration of the exercise qi-gong with open eyes and closed eyes, and to evaluate changes in the distribution of the scalp alpha activity with native EEG before and after the exercise. The observed research file was created from five probands between the ages of twenty-seven to fifty-two, which all practiced qi-gong for a duration of at least twelve months. The results showed the presence of alpha activity during exercising qi-gong with closed eyes in four probands, and in three probands there was also a present alpha activity during the exercise of qi-gong with open eyes. Furthermore was proven that the change in distribution of alpha activity during exercise of qi-gong with open eyes was from parietooccipital regions going temporo-frontally in comparison with the exercise of qi- gong with closed eyes and native EEG before and after exercise. The acquired results support in literature the described change of generators of alpha activity localized in the deeper structures of the brain. This process is connected with the decreased activity of the cerebral cortex with an increase in the particular limbic structures....
